Harry Moseley, aged 11, from Sheldon, and Owen Allen, six, from Bromsgrove, had a starring role at a Cancer Research UK party to salute the courage of children copying with cancer.

I’m A Celebrity winner Stacey Solomon, Dancing on Ice finalist Laura Hamilton and former Hollyoaks actresses Loui Batley and Roxanne McKee praised the youngsters at the ceremony at London Zoo on Saturday.

Owen, who went along with his dad Peter, was diagnosed with Hodgkin’s Lymphoma before Christmas after his mum noticed lumps in his neck.

Despite undergoing surgery and chemotherapy, Owen has never complained and stays positive.

Dad Peter said: “We had a really fantastic day. We were all made to feel really special and it was good to meet other families going through what we’re going through.”

Harry, who was diagnosed with an inoperable brain tumour four years ago, has become a well known figure for his Help Harry Help Others campaign that involves selling hand-made bracelets to raise cash for other sufferers.

The Blakenhale Primary School pupil was diagnosed in 2007 but cannot undergo surgery because of the position of the tumour at the front of his brain.

Stacey Solomon, who attended the party with her son Zac, said: “It has been an absolute pleasure to be part of such a wonderful day.

“I have met so many fantastic families and the children are exceptional, just gorgeous.

“I can’t believe how strong they are when they’ve been through such a terrible time.

“Little Stars are the best – just wicked.”

The event is sponsored by TK Maxx in order to bring a ray of light to children battling various forms of cancer.

Cancer Research UK, the world’s leading cancer charity, spent £10.4 million on research into children’s cancers last year.
